Is there a scientific explanation for this?

Question

When I'm ready for bed, all lights are closed and my eyes are shut. Sudden noise would sometimes come from some place (outside, TV, ...). The noise doesn't matter. My eyes are shut, but when I hear this sudden noise, I see static or lines that appear at that same instant then go away just like that. What is this called?

Answer 1

It's like when you look at a bright light or the sun and you close your eyes, then you see those colored spots that morphs by themselves for a while. For sounds, well, I guess you are strongly of the auditive cognition and it induces this same natural effect.

Answer 2

LSD
